<p>I got a call from an interviewer on Monday and scheduled an interview next Friday. But today, I got an email from a different interviewer wishing to set up an interview some time next week. They're both from Princeton--should I do both, or reject one of them?</p>
<p>Inform the second one that you have already been contacted. You probably only have to do one of these, but say that you'd be more than happy to do a 2nd.</p>
